view color images & scientific plots in ssh terminal, (screenshots using putty ssh terminal included),
Project description
################################################################################
asciiporn is designed for interactive graphics viewing within an ssh terminal
by converting graphics into colorized ascii-art. asciiporn has 256 color support
& is partially written in c for efficent graphics rendering.
asciiporn can easily render 24 bit megapixel graphics on a 1ghz 500mb machine
screenshots of both image viewing & plotting r included w/ this distribution.
asciiporn is hard-coded with lucida-console font, but courier font will work
as well. the screenshots show putty ssh w/ lucida-console 5pt.

how to enable 256 color in xterm: http://www.frexx.de/xterm-256-notes/
how to enable 256 color in screen: http://www.frexx.de/xterm-256-notes/
here are some quick example usage (within an ssh terminal):
>>> ## print image file as colorized ascii art in ssh terminal
>>> from asciiporn import img2txt
>>> print img2txt("mario.gif")
>>> ## plot several math functions in ssh terminal
>>> from asciiporn import plot
>>> from math import cos, sin, pi
>>> print plot(ft = [cos, sin], tmin = 0.0, tmax = 2*pi)
>>> ## plot 3d function in ssh terminal
>>> from asciiporn import plot3d
>>> from math import sin, pi
>>> print plot3d(
... ftz = lambda t, z: sin(t + t*z), ## 3d function
... tmin = 0.0, tmax = 2*pi, ## t parameter
... zmin = 0.0, zmax = 0.25, ## z parameter
... )

REQUIREMENTS:
- posix os
- Python Imaging Library http://www.pythonware.com/products/pil
- numpy http://www.scipy.org/Download
PSEUDOMETHOD:
asciiporn uses ".." syntax notation for pseudomethods
goto: http://pypi.python.org/pypi/pseudomethod
for more details about this feature
API:
asciiporn module:
- img2plaintxt - converts image file to portable plain txt
u can copy & paste in documents
- img2txt - converts image to high-quality colorized txt
for display on terminals supporting 256 color (putty, xterm...)
- plot - plot multiple 2d functions
- plot3d - plots a 3d function that takes in 2 parameters
INSTALL:
python setup.py build
python setup.py install
python setup.py dev --quicktest
################################################################################
PLOT USAGE:
2d plots take 3 main arguments:
ft - a list of functions to plot
tmin, tmax - range of t
>>> import asciiporn, numpy
>>> asciiporn.plot(
... ft = [ ## list of single argument functions f(t)
... numpy.cos,
... numpy.sin,
... lambda t: numpy.sin(t + 0.25),
... ],
... tmin = 0.0, tmax = 7.0, ## range of t
... )

3d plots have 2 extra arguments:
zmin, zmax - range of z
>>> import asciiporn, numpy
>>> asciiporn.plot3d(
... ftz = lambda t, z: numpy.sin(t + t*z), ## 3d function f(t, z)
... tmin = 0.0, tmax = 7.0, ## range of t

asciiporn can also plot user-supplied (y,t) datapoint pairs:
>>> import asciiporn, numpy
>>> t = numpy.arange(1000) ## create t coord datapoints
>>> y = numpy.sin( 0.01*t ) ## create y coord datapoints
>>> yt = list(zip( y, t )) ## create (y,t) datapoint pairs
>>> asciiporn.plot( yt = yt )

IMAGE USAGE:
in this example, u'll b loading the image file included w/ this distribution,
"mario.gif". its a fairly large image, so u prolly want to scale it down
to 0.5 (or less):
>>> colortxt = asciiporn.img2txt("mario.gif", scale = 0.5)
>>> print( colortxt )
... beautiful color image appears ^_-
>>> plaintxt = asciiporn.img2plaintxt("mario.gif", scale = 0.5)
>>> print( plaintxt )
... rather plain b/w img -_-, but u can copy & paste in documents ...

actually, the plaintxt prolly won't look well when pasted,
b/c most document readers invert the color:
>>> plaintxt = asciiporn.img2plaintxt('mario.gif', scale = 0.5, invert = True)
>>> print( plaintxt )
... b/w img w/ colors inverted. may look funny now :/
but it'll b normal when pasted in document

RECENT CHANGELOG:
20090407
fixed installation bugs
added retro-gif feature
20090328
removed py3to2 requirement
update documentation
20090103
rewrote 3d plotter
fixed more 64bit issues
20081123
fixed bug where 64bit gets truncated to 32 on 32bit machine
256 color support
20081119
fixed bugs in setup.py
asciiporn is designed for interactive graphics viewing within an ssh terminal
by converting graphics into colorized ascii-art. asciiporn has 256 color support
& is partially written in c for efficent graphics rendering.
asciiporn can easily render 24 bit megapixel graphics on a 1ghz 500mb machine
screenshots of both image viewing & plotting r included w/ this distribution.
asciiporn is hard-coded with lucida-console font, but courier font will work
as well. the screenshots show putty ssh w/ lucida-console 5pt.

################################################################################
PLOT USAGE:
2d plots take 3 main arguments:
ft - a list of functions to plot
tmin, tmax - range of t
>>> import asciiporn, numpy
>>> asciiporn.plot(
... ft = [ ## list of single argument functions f(t)
... numpy.cos,
... numpy.sin,
... lambda t: numpy.sin(t + 0.25),
... ],
... tmin = 0.0, tmax = 7.0, ## range of t
... )

3d plots have 2 extra arguments:
zmin, zmax - range of z
>>> import asciiporn, numpy
>>> asciiporn.plot3d(
... ftz = lambda t, z: numpy.sin(t + t*z), ## 3d function f(t, z)

asciiporn can also plot user-supplied (y,t) datapoint pairs:
>>> import asciiporn, numpy
>>> t = numpy.arange(1000) ## create t coord datapoints
>>> y = numpy.sin( 0.01*t ) ## create y coord datapoints
>>> yt = list(zip( y, t )) ## create (y,t) datapoint pairs
>>> asciiporn.plot( yt = yt )

IMAGE USAGE:
in this example, u'll b loading the image file included w/ this distribution,
"mario.gif". its a fairly large image, so u prolly want to scale it down
to 0.5 (or less):
>>> colortxt = asciiporn.img2txt("mario.gif", scale = 0.5)
>>> print( colortxt )
... beautiful color image appears ^_-
>>> plaintxt = asciiporn.img2plaintxt("mario.gif", scale = 0.5)
>>> print( plaintxt )
... rather plain b/w img -_-, but u can copy & paste in documents ...

actually, the plaintxt prolly won't look well when pasted,
b/c most document readers invert the color:
>>> plaintxt = asciiporn.img2plaintxt('mario.gif', scale = 0.5, invert = True)
>>> print( plaintxt )
... b/w img w/ colors inverted. may look funny now :/
but it'll b normal when pasted in document
